IVILLIAM F. RUDOLPH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE IVELSBAOH LIGHT COMPANY, OF GLOUCESTER CITY, NEIV JERSEY.

ANTlVlBRATlON-BURNER FOR INCANDESCENT GAS-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 615,309, dated December 6, 1898. Application filed May 2, 1896. Serial No. 589,939. (No model.)

To all whom it may concern:

Be it known that I,WILLIAM F. RUDOLPH, a citizen of the United States, residing at Ihiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Antivibration Lamp or Burner for Welsbach or other Incandescent Gas-Lights, of which the following is a specification.

The principal object of my present inven= tion is to provide a compact, attractive, and efficient antivibration burner or lamp for Welsbach and other incandescent gas-lights; and to this end my invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part thereof, and in which Figure 1 is a side elevational view of a burner or lamp embodying features of my invention. the same, partly in section, taken in a plane at right angles to the plane of Fig. 1. Fig. 8 is an enlarged central sectional view showing the burner cap or tip carried by a springsupport arising from the Bunsen tube and provided with a mouth forming with the Bunsen tube a loose lap connection, and Fig. 4 is a sectional view taken on the line 1 1 of Fig. 3.

In the drawings, 1 is a Bunsen tube adapted for attachment to a gas-fixture, bracket, or-

similar device.

2 is agallery connected with the Bunsen tube 1 and constructed-for example, as at 3- so as to clear the burner cap or tip 4:. The latter is provided with a carrier 5, from which the mantle 6 is suspended. The under side of the cap or tip 4 is provided with a mouth 7, larger in diameter than the Bunsen tube 1 and forming therewith a loose lap connection, which arrangement permits one part to move freely in all directions in relation to the other.

8 is a spring-support connected at its upper end with the burner tip or cap 4:=for example, as shown in the drawings. The Bunsen Fig. 2 is a side elevational view of tube may be passed through and fitted to a sleeve 9, attached to the lower portion of the gallery. The springsupport 8 is suitably connected at its lower end with the lower portion of the device and rises around and from the Bunsen tube.

The mode of operation of the hereinabovedescribed antivibration lamp or burner is as follows: The spring-support 8 carries the man tle, in the present instance, through the intervention of the parts 4 and 5 and prevents lateral and vertical vibrations of the mantle when shocks or jars are imparted to the bracket, fixture, or other part to which the Bunsen tube is connected at its lower end. The loose lap connection formed by the mouth 7 and upper end of the Bunsen tube serves to supply gas without interfering with the described action of the spring-support, because it comprises in efiect a universal joint or arrangement by which one part may be made to move freely in all directions in relation to the other.

It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in details. without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination in an incandescent gasburner of a Bunsen tube, a cap having a mouth forming with the Bunsen tube a universally-jointed loose lap connection, a mantle carried by the cap, and a spring interposed between the cap and tube, substantially as described.

In testimony whereof I have hereunto signed my name.

WILLIAM F. RUDOLPH.
